It’ not just the general manager and head coach who will be gone in 2013.

Depending on who you talk to, the Chargers are a disaster in need of FEMA or just a few pieces from a full set.

We don’t know who exactly will be making the personnel decisions, so we can’t know all the dominoes that will fall.

But expect that a number of big names and longtime Chargers won’t be around in 2013. In fact, given the state of the team and status of so many contracts, it is likely the makeover will rival that of 2004, when A.J. Smith remade the roster in his second spring in charge.

• The Chargers knew it was a risk when they signed left tackle Jared Gaither to a $24.5 million contract, given his injury history and reputation for milking those injuries and not working hard. They couldn’t have imagined it would be like this. Several teammates are absolutely finished with Gaither, and it’s difficult to see him being welcomed back into the locker room, despite the $9 million paid to him in 2012 bonus and salary and the $6 million cap hit his release would cost.

• The consensus among football people here and around the league is that outside linebacker Larry English just won’t ever be a difference maker at the NFL level – healthy or not. The Chargers’ 2009 first-round pick has one year left on his contract, but it’s almost impossible to imagine a scenario he is kept after playing fewer than 1,000 snaps so far in his career.

• Shaun Phillips is bouncing back in a contract year. But the man who has started 103 games over the past seven seasons and ranks second in team history with 67 sacks will almost certainly get his next paycheck from another team. He’ll be 32 in 2013, and he won’t be looking to be the other guy again, this time behind 2012 first-round pick Melvin Ingram.

• The Chargers were compelled to guarantee right tackle Jeromey Clary $6.8 million prior to the 2011 season. He’s due $4 million if he’s on the roster next season. Dependable and hard working, Clary’s struggle with speed has become too much of a liability. The $3.4 million cap hit the Chargers would take is a deterrent, especially with so many other moves to be made.

• If Clary goes, and with the likely departure of left guard Tyronne Green, free-agent-to-be Louis Vasquez is in an even more advantageous position than his consistent play in 2012 afforded him. With so many other holes to fill, it is almost imperative they keep Vasquez.

• If the Chargers keep running back Ryan Mathews, which his talent dictates they do for one more season, they at least need to find another top-flight back for his inevitable time out. Largely due to injury, but also because of fumbles and his inability to adequately pick up pass protection and certain parts of the offense, Mathews has played the equivalent of two seasons since the Chargers moved up 16 spots to draft him 12th overall in 2010.
